Sulfur Cinquefoil has reasonably attractive flowers and foliage. The latter has some resemblance to the foliage of Cannabis sativa (Marijuana). However, Marijuana is usually a taller plant with very different flowers. Its leaflets are narrowly ovate and longer than the leaflets of Sulfur Cinquefoil. There are many kinds of Cinquefoils, both native and introduced, that are often hard to tell apart. Sulfur Cinquefoil can be distinguished by its erect habit, palmate leaves with 5 or 7 leaflets, pale yellow petals that are longer than the sepals, and terminal clusters of flowers. Other species of Cinquefoils have stems that are sprawling or stoloniferous, palmate leaves with only 3 leaflets, bright yellow petals that are no longer or shorter than the sepals, or flowers that develop individually from the leaf axils.
